Should I get a DME reflash or the JB4?
The JB4 offers unique advantages not found in flash tunes including on the fly steering wheel control map switching, an optional in dash boost gauge and shift light, auto tuning to ensure you always have the safest and most powerful tune for your particular conditions and modifications, built in code management, optional race gas and higher performance mapping, methanol integration, and for more advanced users a full user adjustable tuning interface. For those with leased vehicles or those under factory warranty the JB4 offers the ability to be removed without a trace. With its full CANbus integration the JB4 has access to every piece of information the DME does and thus can provide factory smooth mapping with reduced turbo lag and much stronger power outputs. Truly how the vehicle should have come from the factory. All of this for generally half the price of flash tuning in a package that can be installed and removed at home in under thirty minutes.
